When Ambar Disla turned 13 last year, she was in the hospital battling bone cancer.

Tomorrow she turns 14. She’s still battling cancer, but this time she intends to spend her birthday dancing in a “Zumbathon” with her friends at Merrimack Valley Middle School.

“Zumba for Ambar” will start at 6:30 p.m. and feature the fitness program popular with millions worldwide and inspired by a variety of Latin dances.

It’s one of the ways Ambar, a freshman at Merrimack Valley High School who is facing cancer for the second time in her life, likes to spend her free time. Her story has been featured in the Monitor over the last several months.

If you’ve never done Zumba before, you’re invited to come from 6 to 6:15 p.m. to learn the basics. The event will also have raffles.

The suggested donation for the event is $5. The family lives in Penacook and has been struggling to keep pace with the bills associated with Ambar’s care, which has included several rounds of chemotherapy and radiation at Dartmouth-Hitchcok and Massachusetts General Hospital.

If you’d like to help the family but can’t make the event, you can make a check out to Ambar’s Family Trust and send it to P.O. Box 906, Concord, N.H. 03303.

To follow Ambar’s journey, you can find her at “Ambar Disla Family Support” on Facebook.
